I. INTRODUCTION
A recent on Australian sorghum by Selle et al. (2017) that sorghum produced in Australia is used almost exclusively for feed, especially cattle, pigs and poultry. The objective of the present study is to assess the response of broiler chickens to diets based on sorghum, when supplemented with a combination of enzymes, targeting different substrates.

Calcium is an important cation in chicken diets, being the most abundant element in the body of the chicken. Its functions include: mineralization of bones, blood clotting, enzyme activation, neuromuscular function, muscle contraction, and intracellular signaling. However, high dietary Ca is a limiting factor for phytase efficacy and the formation of insoluble Ca-phytate complexes decreases Ca and ...

This study was aimed at assessing endogenous enzyme activities and utilisation of metabolisable energy by broiler chickens fed maize-based diets supplemented with phytase and carbohydrases. Birds were raised in cages in climate-controlled rooms. The jejunum and pancreas were collected at 10 and 24 d for analysis of endogenous digestive enzyme activities. Birds were also sampled at hatch and 24 d a ...

Supplementing poultry diets with xylanase partially depolymerizes the xylans present in the dietary cereals, reducing the number of sugars in the molecular chains. The resulting oligosaccharides can be selectively fermented by beneficial intestinal bacteria, resulting in improved nutrient utilization (De Maesschalck et al., 2015). The study aim was to investigate the production of xylo-oligosaccha ...

Supplemental xylanase may be used in diet formulation to reduce diet cost, mitigate the antinutritive effects of arabinoxylans, increase energy utilization, and improve growth performance of broilers. Xylanase has been shown to partially depolymerize arabinoxylans, which can reduce intestinal viscosity, reduce nutrient encapsulation, and modulate the intestinal microflora of broilers (Choct et al. ...

DESCRIPTION OF PROBLEM
Phytase has been regularly incorporated into commercial poultry diets due to its relatively low cost and effectiveness at hydrolyzing phytate (IP6; myo-inositol 1, 2, 3, 4, 5, 6-hexakis dihydrogen phosphate; Bedford and Cowieson, 2009). Dephosphorylation through phytase supplementation is needed for birds to access this source of P and also to prevent the chelation of IP6 w ...

1. Introduction
Maize is the most common energy source used in commercial monogastric diets, especially in the American, Southern Europe and most Asian countries where maize grain is the primary cereal for poultry feeds (Dei, 2017). However, the nutritional value of maize for livestock feeding can vary (Cowieson, 2005). Genotype, agronomic conditions and pre- and post-harvest processing can affec ...

Implications
The host DNA in faeces presumably originates from gut cell losses. This development of a non-invasive assessment method is potentially a novel indirect measurement of gut cell losses, although further validation experiments are required. A yeast-inclusion diet significantly reduced pig DNA in faeces and therefore may reduce gut cell losses. Turnover of gut cells contributes to feed e ...
